ANTIJAMNINGSANORDNING FOR EN ELEKTRONISK SVEIPERADAR OG EN RADAR MED EN SLIK ANORDNING

摘要

The radar has the antenna elementary radiators coupled to phase shifters for the electronic beam deflection, with a control circuit allowing the gain of the antenna to be reduced in the direction of a noise transmitter. A single auxiliary antenna (5) indicates the direction of different noise transmitters in succession, its signal being summed with the electronic scanning antenna (1) to allow the phase angle of selected phase shifters to be modified.The elementary radiators are divided into two groups of parallel lines spaced apart by a constant distance and the two groups offset by a quarter of the distance between lines in the same group.
